ク。 A deflection yoke attached to an in-line color picture tube, which has a right side part and a pair of long legs on the inside symmetrical with respect to the center of the right side part and extending in the same direction from the right side part. A vertical magnetic field corrector comprising a pair of comb-shaped magnetic cores having a pair of short legs and an auxiliary coil wound around the center of the right side of the comb-shaped magnetic core is installed on the electron gun side of the deflection yoke. In the deflection yoke, in which the magnetic core legs of the pair of vertical magnetic field correctors are arranged facing each other orthogonally to the in-line arrayed electron beam near the opening, the outer legs of the comb-shaped magnetic cores of the vertical magnetic field correctors are A deflection yoke characterized in that a comb-shaped magnetic core is formed so that its tip approaches the screen surface side of a picture tube.
